It works with any cellphone using Google’s photo sphere stitching technology, but the app also now supports dedicated 360-degree cameras, like Ricoh’s Theta S camera, announced earlier today.

Aside from the fun of uploading your own content for the world to see, the new functionality helps Google flesh out its Street View content without sending out more 360-degree camera rigs; it could be especially useful for mapping the interiors of businesses and restaurants. That said, there’s no word on how the images are being curated, but we imagine Google will want to prevent poor quality or inappropriate images from staying on Maps.
